You will receive a zero for any answers that result in a wrong answer. Show your work so your instructor can see where you made the mistake. When minor mistakes are made, only a few points will be deducted.

Typing the answers is acceptable but time consuming. Alternatively, you can scan or take a photo with your smart phone and send as an attachment.

1. What are the g loads on an aircraft when it banks at 10, 20, 60, 70 and 80 degrees?

2. What happens to the g load over 80 degrees?

3. What is a negative g load?

Hint, if you have ever been on an aircraft where there have been ‘air-pockets'.

4. What does the Normal Operating Range represent on a V-g diagram?

5. Why do fighters have additional areas on a V-g diagram? Give an example where this may be needed.

6. ‘I' beams are used in the ordination to show the shape in an ‘I' form. What happens when they are used in the ‘H' form?

Hint, where is the majority of the material.

7. Modern aircraft have several spars (Beams); how does this make the wing stronger to resist the weight of engines and loads during flying?

8. Why is there zero stress at the neutral? Hint, what was your answer in Q 7 above.

9. Select one of the following beams in table 1 below, and calculate the ‘I' value if the section thickness is 20 mm.

Hint, you need to subtract the area where there is no material.

10. What happens to the stress values if the engines are mounted above the wing as shown below in Figure 1?

11. Why are the units for an ‘I' value m4?

12. The section beyond the last engine, what stress is within this part of the wing? (up to 5points)
